Convertibles
Need a PC that can serve double duty as a notebook and a tablet? The burgeoning convertible market has you covered. Since we last checked in, Microsoft has traded ARM CPUs in its entry-level Surfaces for Intel's Cherry Trail Atom processors, which makes them a compelling enough product to warrant inclusion here.

Microsoft Surface 3With its Surface 3, Microsoft sheds the hobbled Windows RT and ARM CPUs of the Surface and Surface 2 for full-fat Windows and an Intel Cherry Trail Atom CPU. This new slate is a lot like a shrunken Surface Pro 3, and that's a good thing. It inherits the 3:2 aspect ratio display from its larger, more powerful sibling, as well as the built-in pen digitizer. The Atom CPU isn't going to break any speed records, but it should be more than adequate for most day-to-day work in Windows. Unfortunately, the $500 base price doesn't include a Type Cover keyboard or Surface Pen–those are $130 and $50 extras, respectively.

Asus Transformer Book T300 Chi
One slightly frustrating fact of the convertible world is that the base price of many of these systems doesn't include a keyboard dock. Not so with Asus' Transformer Book T300 Chi. This Transformer offers Intel Core M power, a high-quality keyboard, and a gorgeous screen for only $700, which is the cheapest way to get into a complete convertible here. You do give up the Surface 3's pen digitizer in exchange for the more powerful CPU, but that's probably a reasonable tradeoff for most.

Dell Venue 11 Pro 7000
If you need a business-oriented convertible with the potential for really long battery life, Dell's Venue 11 Pro 7000 is worth a look. This Windows 8.1 tablet starts at $700 with an Intel Core M processor, 4GB of RAM, and 64GB of solid-state storage onboard. Shell out another $220 for Dell's keyboard dock, which turns the system into a clamshell laptop, and the company claims you'll enjoy up to 20 hours of unplugged time. Just make sure to get the "Dell Tablet Keyboard - Mobile" and not the "Dell Tablet Keyboard - Slim." The latter is cheaper but doesn't have a battery built in (or a hinge, for that matter).

Microsoft Surface Pro 3
If you need more computing power or a bigger, higher-res screen than the Surface 3 offers, then consider stepping up to the Surface Pro 3. This more powerful take on Microsoft's tablet formula features low-voltage Haswell Core i3, i5, and i7 CPUs, as well as a 12", 2160x1440 screen and more solid-state storage. The $800 base price gets you a Core i3 CPU, 64GB of storage, 4GB of RAM, and an included Surface Pen. The Type Cover keyboard is still a $130 extra, though.
